I was working with a
sf::RenderTexture but on which I'd draw diffrent stuff. Now at the beginning the rendertexture gets clear with a fully transparent color thus when exctracting the texture later it will only show something at the place I've drawn something.
The problem is now when I want to remove a drawn square I wont' be able to do this, since I can't clear only a specific area and thus have to clear the whole rendertexture and draw everything again.
If I'd use a non transparent background color it would be easy, I'd just draw a shape over the section I want to remove but you obviously can't draw a transparent shape over something, because it will just shine through.
Am I missing a function here or any other possibilty that doesn't involve direct OpenGL calls or clearing the whole rendertexture?
If not, consider this a feature request...
